|
M1562 was not qualified during a full test since the test did not complete.
Looking at the module I see that roc 2 has a lot of noise row 79.
I tried to mask all pixels in this row but the masking does not work.

Fri Feb 14 14:05:16 2020, Dinko Ferencek, Module assembly, Production yield so far
|
Of 41 modules produced and tested so far (1536-1576), 6 modules were found to be [COLOR=red]bad[/COLOR] before or during the reception test, 5 were graded
[COLOR=red]C[/COLOR] after the full qualification (one of which is possibly [COLOR=orange]C*[/COLOR]) and the remaining 30 modules were graded [COLOR=darkblue]B[/COLOR]
(of which 4 were manually regraded from [COLOR=red]C[/COLOR] to [COLOR=darkblue]B[/COLOR]).

Wed Feb 12 11:15:04 2020, Dinko Ferencek, Module grading, Problem with dead trimbits understood 14x
|
It was noticed that some modules are graded [COLOR=red]C[/COLOR] because of typically just one ROC having a large number of dead trimbits. One example is
ROC 10 in M1537

The procedure for manual grading is described in [URL=https://github.com/psi46/MoReWeb/pull/120]https://github.com/psi46/MoReWeb/pull/120[/URL].
In short, inside the test folder it is necessary to place a text file called [I]grade.txt[/I] that contains just one number representing the manual grade:
